Title: Immersion nozzle of tundish
Inventor: NAKAGAWA HIROMITSU
IPC: B22D11/10
Filed: 1986-10-24
Abstract: PURPOSE:To improve the quality of an ingot by forming nozzle holes to the peripheral face of a cylindrical bottomed nozzle and disposing discharge guiding members in the holes. CONSTITUTION:A tundish 3 is disposed to a water-cooled casting mold 1 and the immersion nozzle 6 is installed to the bottom thereof. The nozzle 6 has a cylindrical bottomed nozzle body 7, two pieces of the nozzle holes 8 and the discharge guiding members 9. Flow regulating plates 11 are disposed in the members 9. A molten steel poured into a casting mold 1 is guided and discharged by the members 9 and, therefore, the regular convection of the molten steel in the mold 1 is obtd. and the range where the convection reaches is shallowed. The temp. difference between the surface and central part of a solidified shell is thereby decreased and the generation of bulging, central segregation, porosity, and internal crazing is prevented. The plates 11 rotate the molten steel around the axial center of the members 9 to intensity the lateral spread of the molten steel and to prevent the generation of the defects. The quality of the ingot is thus improved.

Abstract: PURPOSE:To improve heat dissipation and to reduce a weight by dividing a stator core of a rotary electric machine into a slit forming part of an inner peripheral side and a cylindrical part for forming a magnetic path of an outer peripheral side, and forming the cylindrical part of the outer peripheral side of magnetic aluminum alloy material integrally with a housing. CONSTITUTION:A housing 1 is formed of magnetic aluminum alloy material, and a thick part 1b is formed at a part corresponding to an outer periphery of a stator core 2. A core formed only of a cylindrical part having slots and a toothed part is provided at its inner peripheral side. The cylindrical part for forming a magnetic path of the outer periphery is divided, and formed of the part 1b of the housing 1. The alloy is formed by mixing aluminum powder and ferromagnetic material, solidifying and molding it and has ferromagnetic characteristics and high rigidity. A cylindrical state formed of the alloy integrated with the housing forms a magnetic path of a stator core to reduce a quantity of a core formed of a laminate of silicon steel plates.

At an front end 6, the processing dependent mainly on the source program is carried out and an intermediate code is generated. An intermediate code merger processing part 7 merges the intermediate code generated at the end 6 with the intermediate code which is generated in the precedent compiling state. This merger processing is carried out based on the value shown by the series number of sentences.

Title: Hot rolling method of continuous casting slab for grain-oriented silicon steel sheet
Inventor: KUROSAWA MITSUMASA
IPC: C21D8/12
Filed: 1984-12-04
Abstract: PURPOSE:To minimize the edge roughening generated during hot rolling and to improve the yield of a steel sheet in the stage of subjecting a continuous casting slab consisting of a silicon steel to hot rolling and cold rolling then to annealing to produce the grain oriented silicon steel sheet by controlling the flatness on the side face of a sheet bar prior to the finish rolling in the hot rolling stage to a specific value. CONSTITUTION:The continuous casting slab consisting of the silicon steel contg. 2.5-4.0wt% Si is heated to a temp. range of 1,250-1,420 deg.C and after the slab is descaled, the slab is rolled to the sheet bar by a roughing mill and is further finished to a hot coil by a finishing mill. The hot finish rolling is executed in this case by controlling the flatness F on the side face of the sheet bar in the stage of the rough rolling to <=1.3. to minimize the edge roughening to be generated at the transverse edges of the hot coil. The hot coil is then subjected to decarburization and primary recrystallization annealing, secondary recrystallization annealing and purification annealing, by which the grain oriented silicon steel sheet is produced. The rupture in the cold rolling stage is eliminated by minimizing the edge roughing of the hot coil, by which the yield of the product is improved.

Title: Discharge lamp lighting device
Inventor: ONISHI MASAHITO
IPC: H05B41/282
Filed: 1990-09-25
Abstract: PURPOSE:To reduce peak value variation and to realize a low noise by providing an impedance element for continuously feeding an electric current to a discharge lamp when a switching element is off so as to continuously feed a current to the lamp via the impedance element. CONSTITUTION:An impedance element Z1 is connected in parallel to a switching element SW and when the element SW is turned on by a drive signal a power source voltage E is applied to a lamp 1. In the case where the element Z1 is of such resistivity and inductivity as not to increase a lamp current IL, turning-on of the element SW increases the current IL and turning-off thereof applies a voltage to the lamp 1 via the element Z1 to flow a gradually reducing current. When the impedance element Z1 is capacitive, storing of energy in the element Z1 reduces a current thereto and the lamp current IL becomes a gradually reducing waveform similarly. Accordingly, a high frequency component is reduced to reduce generation of a noise.

Title: Pointing device
Inventor: KATO YOSHIBUMI
IPC: G06F3/038
Filed: 1989-09-28
Abstract: PURPOSE:To prevent the change of the position of a mouse cursor, i.e., a pointing position despite the minute movement of a mouse by providing a hysteresis generating circuit after a mouse driver. CONSTITUTION:A mouse 1 which produces manually the 2-dimensional movements is provided together with an address generating circuit (mouse driver) 2 which produces the addresses in response to the movement of the mouse 1, and a hysteresis generating circuit 3 which gives the hysteresis to each address. When a mouse 1 is moved on a desk, etc., the driver 2 produces a distance DELTAx (DELTAy) moved relatively to the moved position of the mouse 1. The distance DELTAx (DELTAy) is changed into DELTAx' (DELTAy') via the circuit 3. Thus the output DELTAx' (DELTAy') has no change when the mouse 1 moves by a minute distance. As a result, a mouse cursor does not move at all and therefore the influences of the hand shaking, etc., can be eliminated.
